Description

The p.V490I variant (also known as c.1468G>A), located in coding exon 13 of the PTPN11 gene, results from a G to A substitution at nucleotide position 1468. The valine at codon 490 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
